Device linking method

ABSTRACT

Systems, methods, architectures, and computer program products for linking multiple devices are disclosed. In an example for linking a mobile device with a desktop device, an identifier of a mobile device can be received from a desktop computer. The identifier can be used to send a link to the mobile device. When the link is accessed, a code and a channel are generated. The mobile device is connected to the channel and the code is provided to the mobile device. The code is entered at the desktop device and the desktop device is connected to the channel responsive to the code being validated, thereby linking the desktop and mobile devices.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/341,765, filed Nov. 2, 2016, entitled, “Device Linking Method,” which claims priority to U.S. Provisional Patent Application Ser. Nos.: 62/251,942, filed Nov. 6, 2015, entitled “Device Linking System and Method”; and 62/372,437, filed Aug. 9, 2016, entitled “Device Linking System and Method.” Both of the above-referenced applications are hereby incorporated by reference herein in their entireties.

BACKGROUND

The smartphone has significant data input and acquisition functionality that traditional desktop computers do not have. These include touch screen technology, built-in cameras, video cameras, accelerometers and GPS sensors. The desktop computer commonly has a keyboard and mouse as the only means of data entry.

In many instances, it would be convenient to link a user interface on a desktop computer with a user's smartphone, tablet or other mobile device, to allow the user to access the broad capability for data input, acquisition and output of the smartphone or other device. In some cases, however, security and privacy issues may arise when linking a smartphone with a desktop. For example, privacy issues are always important to address when dealing with medical records of patients in a hospital or clinic setting. Previously described methods and systems for linking devices often lack sufficient security for highly private information such as medical records, or they may be very cumbersome to use, or in some cases both.

Therefore, it would be desirable to have an improved method and system for linking a user interface on a desktop computer with a user's smartphone, tablet and/or other mobile computing device. Ideally, the method and system would be easy to use and also provide adequate security measures so that sensitive, private data could be accessed via the linked device(s). At least some of these objectives will be addressed by the embodiments described below.

DETAILED DESCRIPTION

The following description of various embodiments should not be used to limit the scope of the present invention. Alternative embodiments, features, aspects, variations and advantages are included within the scope.

In various embodiments of the system and method, a user initiates the linking process through a web session on a first device, such as a desktop computer. The user is prompted to enter at least one identifier that can be used to identify the second device, such as a smartphone, tablet or other mobile device, and/or which can be accessed from the second device, such as through a messaging or communication service, including but not limited to electronic mail, browser, link, embedded link, HTML5 notification, emergency notification, text message, photo sharing service, link sharing service, mobile messaging application, and any application, which may be encrypted or not encrypted. Such identifiers include, but are not limited to, an e-mail address, cellular phone number, unique device identifier (UDID), device serial number, International Mobile Station Equipment Identity (IMEI), Integrated Circuit Card ID (ICID), RFID signal, blue tooth signal, device unique power usage profile, device resonance frequency, Mobile Equipment Identifier (MEID) or other identifier tied to the second device or the user thereof.

The identifier is used to send linking information to the second device. This may include, but is not limited to, a web hyperlink sent via short message service (SMS), e-mail, or any type of push notification. The link, when activated, opens a web page and/or application prompting the user to input a second unique identifier, which is concurrently displayed on the screen of the first device. Such second unique identifiers include, but are not limited to, a string of alphabetical and/or numerical characters, images, trademark images, brand images, audible or inaudible sound from a speaker, phrases or any other unique image, signal, form, sequence or code displayed by a device or system. The second unique identifier may also be an object or traceable image or description of an action that a user must undergo with the phone, in order to have the sensors on the phone detect that such an action has taken place, such as but not limited to moving the phone in a specific way, causing the accelerometers to read a pattern, such as tapping in a distinct rhythmic pattern or moving in a figure eight.

The unique identifier may be generated by an algorithm, program, or software, which may reside on the first device, second device, or on an alternate location, including but not limited to a server or third device. The unique identifier may be specifically generated for a single session between the receiving and collecting device, or be used to link the two devices on a long-term basis. Auxiliary services for generating or reading the unique identifier may be used.

Communication between devices may occur through a wireless or wired connection, including but not limited to the Internet, wifi, Bluetooth, radio waves, microwaves, or other electromagnetic waves capable of transmitting data.

Once linked, the first device and second device may be used to display or acquire data for the other device. For example, one device may collect any type of data, including but not limited to images or text generated through a user touching a touch screen, typed data from a keypad, sound captured from a microphone, pictures or video captured from a camera, or other information recorded from a sensor, such as a RFID, infra-red sensor, magnetic sensor, or other means. Such data acquisition features may be built into the device or add-on or peripheral devices. Such data from the first device may then be transferred in whole or in part and displayed on the second device, and vice versa, and/or stored elsewhere, including a third device or server. The data may be sent from the first device to the second device instantaneously or stored on the collecting device or an intermediate device until a later time.

The user or users may acquire data using the collecting device and direct its placement to the receiving device. For example, if the collecting device is used to collect a signature generated from its touch screen, the user may direct where the signature image is to appear on the receiving device. In this instance, the user may select a place on a document they are viewing or editing on the receiving device for the signature to appear.

The receiving device may also direct the type of data to be collected by the collecting device. For example, if a user opens a web page on the receiving device, whose purpose in part or in whole is to contain a picture, the receiving device may remotely activate the camera on the collecting device to capture the desired image. If there is a web page on the receiving device whose purpose, in part or in whole, is to collect a sound recording, the receiving device may remotely activate the microphone. If there is a web page on the receiving device whose purpose, in part or in whole, is to collect a signature, the receiving device may remotely activate a blank web page or otherwise activate the touch screen in order to collect the signature from the touch screen.

Alternatively, the user may select the desired functionality for data acquisition through an application, web page or other means on the collecting device, or through an application, web page or other means on the receiving device, including but not limited to mouse clicking icons that direct the type of data to be collected, using mouse clicks to direct the location of data on a web page, document or other digital media on the receiving device.

Alternative workflows for how the first device is linked to the second device may include a variety of scenarios where a unique identifier is displayed on the phone, and then the computer prompts the user to input the unique identifier onto the computer. The first step of this workflow may include the user inputting an email, phone number, or other identifying feature as to where the computer would send a message with a link to a second device, such as but not limited to a tablet, other computer, or smartphone. Once the link is sent from the computer, the user interface on the computer would change to allow for capturing an input of the unique identifier from the user. Also, once the link is sent from the computer it is received by a second device in a format such as but not limited to a packet, email, text message, sms, message code, certificate, or other messaging paradigm. That message is accessible by the user or a system with the user's second device, In this embodiment, the link would be activated by the user or system when the second device receives the message. This may be done automatically or by the user by completing a user action, such as but not limited to clicking or selecting or touching a link on a message such as an email or text message. Once the link is activated it opens a webpage on the second device which would display a unique code or identifier on the 2^(nd) device. This display may include a countdown timer or time out after a period of time, although it does not necessarily need to do these tasks. The unique code or identifier is used by the user or their device as the input into a user interface or system from the first device, in order for the first device to validate that the second device can gain access to the system. The benefits of this paradigm may include being more secure, because it may, but not necessarily, demand that the user of the second device have physical or at least remote access to the first device. In the case of a hospital medical record system, this would mean that the user of the second device must have the ability to log into the system on the first device, which would allow for the code to be generated and sent to the second device and also the interface or capability that would allow for that code to be input on the first device in order to allow for authentication of the second device to link securely to the first device.

FIG. 1A shows an exemplary web session 101 on a first device, in which the user is provided instructions 102 on entering an identifying code for a second device, here a phone number 103 or an e-mail address 104. Once the identifier is entered, the data are submitted 105 and a linking status is also displayed 106

FIG. 1B shows an exemplary web session on a first device in which the user has entered a phone number 107 as the identifier for the second device; no e-mail address has been entered 108 in this example.

FIG. 1C shows an exemplary web session on a first device, once the identifying information has been submitted for linking. A status message 109 and linking code 110 are displayed.

FIG. 1D shows an exemplary web session on a first device, once the identifying information has been submitted for linking. A status message and a follow the leader display, illustrating a video of the linking code as a movement 111, prompts the user to move the device to be linked in a specific pattern relative to the screen, in order to read the signal and link the devices.

FIG. 1E shows an exemplary web session on a first device once the identifying information has been submitted for linking. A status message and a display similar to a music play-along game prompts the user to move the device to be linked in a specific pattern, in order to link the two devices, using the movement as the code 112.

FIG. 2A shows an exemplary second device, here a smartphone 201, in which a link is received and displayed 202, with an instruction to click on the link. FIG. 2B shows the exemplary smartphone 201 with a data entry screen shown to enter the authentication code 203. FIG. 2C shows the exemplary smartphone 201 after linking where the desired linked content is displayed 204.

FIG. 3 shows exemplary data flow between a first device 301, a second device 302 and a server 303, to perform the linking process. First, the server 303 sends a web display for user entry of the identifier for the second device 302 to the first device 301, 304. The user enters the desired identifier 305, and an authentication code is returned and displayed on the first device 306. A link is then sent to the second device 307, which when activated by the user 308 prompts the display of a data entry screen for the authentication code 309. The user enters the authentication code 310 to complete the linking process.

FIG. 4 shows exemplary data flow between the first device 401, second device 402 and a server 403, once they are linked. Data 404 may be received from the first device 401, which may or may not be user entered, and may be displayed on the second device 406. Similarly, data 407 from the second device 402 may be sent 405 to the first device 401. In fact, data may be sent to each respective device 408 depending on the flow of the session and user behavior.

FIG. 5A shows an exemplary linking flow, in which the user logs into to a web interface on a first device 501, enters identifying information for the second device 502 and is asked whether he/she wishes to save their linking information for future automated linking 503. If the user selects this option, the identifying information for the second device is associated with the user and saved accordingly 504.

FIG. 5B shows an exemplary linking flow, in which the user has previously indicated a desire to link the first device to the second device, as in FIG. 5A. After the user has logged in 505 to the first device, the user is asked is he/she wishes to link to the second device 506. If the user indicates an affirmative choice, a link is sent to the second device automatically 507, based on previously stored identifying information for the second device, and a link is established 508.

The device may send an email, SMS, text, or other message to the email address added by the user 606 to the linking feature 602 user input interface after the submit button is clicked 604. It is also noted that the submit feature may happen automatically once a pre-defined set of characteristics are met in the email address identifier submission 606 without a user needing to click submit 604.

FIG. 6E shows an exemplary user interface flow for an electronic documentation system 601 that contains a secondary device linking feature 602 that can be used to link a second device to the session on the cloud based electronic documentation system 601 running on a first device. In this embodiment, the linking feature 602 can be clickable to show an interacting window with instructions for how to link 603 a second device to the session on the first device. The linking feature 602, once a unique user input has been added, may display a status sending or update message 608 indicating the status of the user input message being transmitted to the desired second device as a text message or email. The linking feature 602 also contains a status indicator 605 demonstrating the status of the connection link, and this status indicator 605 is separate from the indicator of sending of a message to a desired device. The status indicator 605 has the principle purpose of demonstrating if a link is live between a second device and a first device's session. Both the status indicator 605 and the status sending or update message 608 may be incorporated into the same workflow user display, or alternatively they may be separate.

FIG. 7 shows an exemplary data process flow for linking a first device 701 with a second device 702 over a server session 703. In a first step, a user would access a web display on a first device 701 for entering a second device 702 identifier 704. When the second device 702 identifier 704 is entered, a message is sent 705 to the server 703, which then sends a link 707 to a second device 702 for the user to activate 708. When the second device 702 identifier 704 is sent to the server 703, the server 703 will also change the web display on the first device 701, to allow for user entry of the authentication code 706. Once the link 708 is activated by the user of the second device 702, the server 703 displays an authentication code 709 to the user of the second device 702, and user then manually enters the authentication code on the first device 701 user interface. The first device 701 would then send the user entered code 710 to the server 703 for validation. Once the code is validated, the server 703 would activate the session link 711 between the first device 701 and second device 702 over the network.

FIG. 8 shows an exemplary data flow diagram demonstrating data flowing from a first device 801 after user input 804 to a server 803 and then the server sending data to adjust the user interface to the first device 806 and also the server 803 sending an access link 807 to a second device 802. The access link 807 may be activated by the user of the second device 802 or may be activated automatically by the second device 802. The server 803 sends the user interface on the second device 802 the authentication code from the server 809. Then the user of the second device 802 manually enters data on the first device 801, which sends the data from the entered code 810 to the server 803. Then the server links the session by sending data 811 to the second device 802 and/or the first device 801 to establish a linked web session.

FIG. 9 shows an exemplary user workflow, where a user logs into a first device 901 and enters data on a first device to identify a destination of a message to be sent to an access point on a second device 902. Then the user activates the link sent in a message to show a code on the second device 903. Then the user would input the code shown on the second device on the first device 904, and once the code is verified, the link between the first and second devices is established 905.

FIGS. 10A-10D illustrate an example link architecture 1000 sequence diagram for a system and method for linking a mobile device and a desktop device. One or more of the previous described embodiments may be implemented using the link architecture 1000. The architecture 1000 can be implemented using any of a variety of programming languages or techniques, including but not limited to ReactJS and JavaScript.

The architecture 1000 can be configured to have higher trust in a desktop device than a mobile device. This can be done for security purposes, and it leverages the trust of the desktop computer. For example, when this example is implemented in a hospital, the desktop computer can be a computer managed by the hospital according to high security standards (e.g., in order to comply with HIPAA or other regulations).

One way the link architecture 1000 can improve security is to have the mobile device join a linking session first, and then have the desktop computer join the session after. If the desktop were to join the session first and then the mobile device joined later, then a malicious party may join the session with the desktop computer, which can cause security concerns for the desktop computer. By having the desktop join the existing, known session, security is improved.

Another improvement made by the architecture 1000 involves the generating of a pairing code (e.g., a six digit code to be displayed on the mobile device for entry on the desktop), until after a user accesses a hyperlink. When the user accesses the link, it creates a new session for that user, which includes generating one or more codes and a channel ID.

Another improvement is the ability to account for link previews. Apple iOS and Google Android operating systems can be configured to perform link previews, whereby the operating system accesses the link and provides a preview of the content on the other side of the link for the viewer. If the link is configured to only generate one code (e.g., for security purposes), then the user may be unable to receive a code, because the link preview process already caused a code to be generated by accessing the link for the preview. In this manner, the link preview burns the code meant for the user. One way to address this problem is to use static links that generate the same code each time the link is accessed. However, that would cause security issues as well. One solution illustrated by the architecture 1000 is for the system to generate multiple codes (e.g., five codes) that are associated with the link. Then, each time the link is accessed, a subsequent pre-generated code is provided. In this manner, the link preview can burn the first code, and the system still has a code to provide to the user.

After the link is accessed by the user, the code is displayed on the mobile device screen. At the desktop, the user is prompted to enter the code displayed on the mobile device screen. Once the code is entered at the desktop, the system can look up that code for that link and then know which channel that mobile device is on. With the channel known, the desktop connects to the channel. An identifier of the session may be stored in a database for later retrieval.

In some embodiments, the channel IDs associated with the session can be saved for later use. For example, a system can perform background tasks and notify both the desktop and mobile devices using the channel IDs. For example, for some processor intensive tasks, such as photo processing, the task can be performed in the background with the devices notified once the task is complete, without needing to refresh the session. In some embodiments, this can be performed as part of a queue-based system, where a worker process can make a call to the mobile link service.

In one embodiment, a user can take a photo of a document using the mobile device. The photo is uploaded to a server for a worker to process in the background. The worker process can determine whether anything is missing in the document (e.g., a signature). The worker process can then send a message to the mobile device, which may show a signature field for example. The user can provide a signature in the signature field on the mobile device, which would then show up in a corrected version of the document on the desktop device. In an alternative embodiment, a process may be employed such that a user can take a picture of a driver's license, and the worker process can extract information from the license and use that information to fill in fields in a form (e.g., a user's name and address). In some embodiments, if a user is actively using the mobile device, the device can send a signal through the session to prevent the desktop device from automatically logging off—the presumption being that if a user is actively using the mobile device and the link session is still active, then the user may want to return to the desktop relatively soon.

In one embodiment, the architecture 1000 can be configured such that the mobile device does not send data directly to a backend server. For example, a webpage can be shown on both the desktop computer and a mobile device. If a user checks a check box on a mobile device, then the check box is checked on the desktop computer (rather than a backend server) and then the desktop computer sends a signal to the server indicating that the checkbox has been checked. This can be especially useful in the medical context, where, to determine whether a document is valid, a physician may need to approve it, which is done on the secure desktop rather than the potentially insecure mobile device.
